合成了稀土铕有机配合物Eu(TTA)3phen以及掺杂过渡金属离子Zn~(2+)的掺杂配合物Zn_(0.4)Eu_(0.6)(TTA)_2phenCl_(0.6)。分别对两个配合物的C、H、N元素分析、等离子体发射光谱(ICP)、红外光谱(IR)、X射线衍射图谱(XRD)、紫外可见光谱(UV-Vis)和荧光光谱(FS)进行了对比分析,结果表明,过渡金属离子Zn~(2+)有效地掺杂到了铕配合物中形成掺杂配合物,并且掺杂后配合物与掺杂前结构类似。紫外光谱显示两种有机配合物都能有效地吸收紫外光,吸收峰主要来自于参与配位的有机配体;荧光光谱结果表明,掺杂过渡金属离子Zn~(2+)对于铕配合物具有荧光增效作用,发射光强度是未掺杂之前的1.5倍,并且对可能的荧光增效原理进行了讨论。
Eu (TTA) 3phen, a rare earth doped organic complex, and Zn_ (0.4) Eu_ (0.6) (TTA) _2phenCl_ (0.6) doped with transition metal ions Zn 2+ were synthesized. C, H, N elemental analysis, ICP, IR, XRD, UV-Vis and fluorescence spectra of two complexes ). The results show that the transition metal ion Zn ~ (2+) is effectively doped into the europium complex to form a doping complex, and the doping complex is similar to that before doping. The UV spectra showed that both of the organic complexes could effectively absorb the UV light and the absorption peak mainly came from the organic ligands involved in coordination. The fluorescence spectra showed that the transition metal ion Zn 2+ had Fluorescence synergism, the emission intensity is 1.5 times before undoped, and discussed the possible principle of fluorescence enhancement.
